Past Research
... I work on the cohomology, structure, and representations of various types of rings, such as Hopf algebras and group-graded algebras. My research program has involved collaborations with many mathematicians, including work with postdocs and graduate students. Below is a summary of some of my past res ...

QUANTUM FIELD THEORY
... an observable meaning to the time dependence of interaction processes. The description of such a process as occurring in the course of time is just as unreal as classical paths are in non-relativistic quantum mechanics. The main problem in Quantum Field Theory is to determine the probability amplitu ...

Quantum Heat Engines and Refrigerators: Continuous Devices
... Our cars, refrigerators, air conditioners, lasers, and power plants are all examples of heat engines. The trend toward miniaturization has not skipped the realm of heat engines, leading to devices on the nano- or even on the atomic scale. Typically, in the practical world, all such devices operate f ...

Quantum Private Information Retrieval - UvA/FNWI
... which case the “answers” to the queries consist not only of one bit, but of blocks of a bits. It depends on the setting which of the parameters are more important than others. For example in data storage and transmission, one would like to have a large δ and small length of the codeword whereas the ...

In this work, we generalize a result from Ref. 12, where the entanglement distillation capacity with one-way LOCC for perfectly known memoryless bipartite quantum sources was determined. Quantum state merging was first considered in Ref. 14, w ...

Inconsistencies of the Adiabatic Theorem and the Berry Phase
... Hence, a possible way out is not to drop off-diagonal terms that are usually done. One has to be careful when to drop and when not to. The statement that matrix elements causing transition to other eigenstates are dropped under adiabatic approximation could lead to internal inconsistencies either MS ...

Pairing in a system of a few attractive fermions in a harmonic trap
... g2 (x) = ρ(2) (0, 0; x, x)/ ρ(2) (0, 0; 0, 0)ρ(2) (x, x; x, x), as a function of the distance x. At small distances the offdiagonal correlation is large and practically constant indicating a two-particle coherence. However, at distances comparable to the size of the correlated pair (compare fig. 3) t ...
